This invention relates to improvements in instruments employed. for examination of the rectum and colon, and the principal object of the invention is to provide an instrument that is readily and easily inserted and .afiords a relatively unobstructed and extended view of the mucous membrane of the gut, 6

In the attached drawings:

With reference to the drawings, the device in its prefer'ed form consists of three double arms 1, 2 and 3, which may be formed of looped wire of sufficient strength and rigidity. The arm 1 is rigidly fixed in a suitable supporting structure consisting of a base member or cross head 1 which is swivelly mounted at its center point 5 at one end of a threaded shaft 6, which shaft has fixed at its other end a handle 7.

The cross head 4 shaped, as shown in Fig. 7, has its extremities bifurcated to form two sets of spaced arms, 8, 8, and 9, 9, respectively. At the part 8 mid section of the cross head is secured the relatively fixed arm 1, apertures or sockets 10, 10, being provided for reception of the ends of this arm; while between the arms 8,. 8 and 9, 9 are pivotally mounted upon pins 11, 11, bell sank levers 12, 12, which respectively carry in' apertures or sockets 13,13, the arms 2 and? The lower ends of the, bell crank levers 12 are connected through links 14, 1a andja clamp 15, with .a sleeve 16 having threaded engagement with the. shaft 6. This sleeve has a knurled flange 17 which constitutes a finger-hold when the device is manipulated, as hereinafter lescribed. It

will be noted that with the. aforedescribed arrangement, the handle 7 projects substantially ata right angle to the arms 1, 2 and 3. Thearms 1, 2 and 3 normall li'e'together,

.as shown in Figs. land 2, an inthisposition are readily insertable into therectum. To. facilitate insertion, the upper curved ends of the arms 1, 2 and 3 are turned inwardly so as to provide what in effect is a smoothly. rounded tip for the instrument. NVhen inserted to the desired extent, the

arms-2and 3 may be spread apart from the arm 1 by holding the knurled flange 17 of the sleeve 16, in one hand and rotating with the other the handle 7 and with it the shaft 6. This feeds the sleeve 16 upwardly on the shaft and spreads the arms 2 and 3, as

illustrated inFigs, 3 and 1, without, how- .ever, affecting their substantial parallelism.

1 Preferablythe arms 2 and 3ar'e made tubular, at least in one branch, to permit the mounting therein of electric wires 18 which are connected with small sockets 19 on the inner side of one .orboth of the branches of the arms 2 and 3, these sockets being adapted to receive small electric bulbs 20. Any desired distribution of these sockets and bulbs maybe had, although in the present instance they are shown, see Fig. 1,

in more or less staggered relation on the two arms, thereby to obtain a more uniform distribution of the light throughout the length of the arms. The arm 1 carries be tween its branches and securely mounted therein a mirror 21.

With the foregoing construction, it will be apparent that with the instrument inserted and the arms 2 and 3 spread as de scribed the mucous membrane of more than two-thirdsof the circumference of the gut will be exposed to view the entire length of the instrument, and that by turning the instrument through a slight angle that portion of the membrane covered by the mirror will be exposed. The instrument provides an efiective device for examining'the mucous membranes.

.curate examination.

For the anus and lower part of the rectum, the instrument as described above will be found adequate for thorough and ac- VVhen introduced at greater depth, however, an auxiliary mirror may be used, as shown in Fig. 15. This mirror 22, which is of smallsize, is an 'ularly arranged upon a shaft and preferably is so mounted upon the shaft that the angle of the mirror may be varied. WVh'en this mirror is introduced, it is possible, by reason of the slight angularity thereof and with the fixed mirror 21, to obtain by reflection a clear viewot portionsof the mucous membrane which otherwise would not be visible.

It will, of course, be understood that the structural details of the device may vary largely, and in Figs. 13 and 14 I have illustrated a modification within the scope of the invention. In this instance, a'rigid annular member E lis employed in which are slidably mounted substantially radial rods 25, 26' and 27. Arms 28, 29 and 30, similar to the arms 1,2 and 3,'previously described, are rigidly secured to the inner ends of the rods125, 26 and 27, respectively. The rods, which are threadedare prevented from turning on the member 24; by keys 31 which'enter longitudinal slots 32 in the said rods, as shown in Fig. 14. In threaded engagement with each of the rods and rotatably secured to the member 24 by retaining plates 33 is a sleeve 34, by turning which the rods may be advanced and retracted to spread apart or bring together the arms 28, 29 and 80, as desired. The operation of this embodiment is in all essential respects the same as that previously de scribed.

I claim:

1. In an instrument for anal examination, the combination with a plurality of substantially parallel arms adapted for insertion in the rectum, of means for spreading said arms transversely while retaining their substantial parallelism, at least one of said arms being hollow and adapted for passage of electric wires, and sockets on the inner side of the arm and connected with said wires and adapted'to receive electric bulbspy;

2. In an instrument for anal examination,

the'combination with a plurality of substantially parallel arms adapted for insertion in the'frectum, of means for spreading said arms transversely while retaining their substantial parallelism, at le astone of saidarms being hollow and adapted for passage of electric wire, sockets on the inner side of the arm and connected with said wires and adapted to ing hollow and adapted for passage of electric wires, sockets on the inner side of the arm and connected with said wires and adapted to receive electric bulbs, a mirror fixed iii one or said arms beneath said electric bulbs, and a movable auxiliary mirror disposed at an angle to said fixed mirror.

l In an instrument for anal examination, the combination with a plurality ofsubstantially parallel arms adapted for insertion in the rectum, of means "for spreading said arms transversely while retaining their substantial parallelism, and illuminating means mounted in at least one of said arms.

5.
